Meanwhile on Melee Islan^W^WGiustini

Log into the web config interface (see dsa-passwords for details)

Go to Manage -> General Config -> Manage Host List and give
the new host a nice nickname (i.e. its name). If you did the
discovery above it should already be listed in the global host
list and you just need to set its name. Else you would also need to
manually set the host's iqn (iscsi qualifiled name) which you can
find on the host in /etc/iscsi/initiatorname.iscsi.

Go to Manage -> General Config -> Manage CHAP to add a new
entry for the new host. Pick the correct node name, and set a
secret for it (N.B.: the maximum is 15, not 16 chars -
the interface and documentation lies). Also setup mutual chap:
As name use giustini's base iqn iqn.1986-03.com.hp:storage.msa2012i.0834d5ecda
and again pick a secret (same constraints as above).

Go to Manage -> Volume Management -> volume menu -> add volume to add
a new volume. Choose volume size and name as you wish (our policy for name
appears to be "<targethost>-<mountpoint or purpose>.
Leave LUN empty (i.e. NONE).

Go to Manage -> Volume Management -> volume mapping and map the
new volume to a free LUN on the new host.

Back on the host

edit /etc/iscsi/iscsid.conf:

set node.session.auth.authmethod = CHAP

set node.session.auth.username to own initiatorname (again, see /etc/iscsi/initiatorname.iscsi)
